Ultraviolet sterilization has the advantages of being colorless, odorless, and chemical-free, but if it is used without protective measures, it will easily cause great harm to the human body. For example, when exposed skin is irradiated by such ultraviolet lamps, redness, swelling, scaling, etc. may occur in mild cases; in severe cases, it may even cause canceration and skin tumors. At the same time, it is also an "invisible killer" of the eyes, which can cause inflammation of the conjunctiva and cornea, and long-term exposure may lead to cataracts. Ultraviolet rays also have the effect of destroying human skin cells, making the skin prematurely senile. Therefore, if you buy a UV Sterilizer lamp, you must keep in mind when using it:

1. When using ultraviolet germicidal lamps, people, animals and plants must leave the scene;

2. Do not stare at the UV Sterilizer lamp for a long time. Ultraviolet rays have certain damage to human skin and mucous membranes. When using ultraviolet disinfection lamps, you should pay attention to protection. You must not look directly at the ultraviolet light source, otherwise your eyes will be injured;

3. When using ultraviolet germicidal lamps, the environment should be kept clean, and there should be no dust and water mist in the air. When the indoor temperature is lower than 20 degrees Celsius or the relative humidity exceeds 50%, the irradiation time should be extended;

4. After using the UV Sterilizer lamp, it is recommended to ventilate for 30 minutes before entering the room.
